Embodiment 1

[0018] A new type of composite reactive printing red dye, using 1.02 moles of cyanuric chloride and 1.01 moles of H acid for primary condensation at 0-5°C, and 1 mole of anthranilic acid diazonium salt at 5-15°C, Coupling under the condition of pH5.5~7.5, add 0.1 mole of N-methylaniline, 0.6 mole of o-methylaniline and 0.3 mole of o-chloroaniline, carry out secondary condensation at pH5.5~7.5, 40~45℃, the obtained The solution is concentrated by membrane and then sprayed dry.

Embodiment 2

[0020] A new type of composite reactive printing red dye, which uses 1.01 moles of cyanuric chloride and 1.0 moles of H acid for primary condensation at 0-5°C, and 1 mole of anthranilic acid diazonium salt for condensation at 5-15°C. , coupled at pH 5.5 to 7.5, adding 0.2 moles of N-methylaniline, 0.6 moles of o-methylaniline and 0.2 moles of o-chloroaniline, and performing secondary condensation at pH 5.5 to 7.5 at 40 to 45°C. The resulting solution is concentrated and sprayed dry.

Embodiment 3

[0022] A new type of composite reactive printing red dye, using 1.0 mole of cyanuric chloride and 1.0 mole of H acid for primary condensation at 0-5°C, and 1 mole of anthranilic acid diazonium salt at 5-15°C, Coupling under the condition of pH5.5~7.5, adding 0.2 mole of N-methylaniline, 0.7 mole of o-methylaniline and 0.1 mole of o-chloroaniline, carrying out secondary condensation at pH5.5~7.5, 40~45℃, the obtained The solution is concentrated by membrane and then sprayed dry.

Abstract

The invention discloses a novel compound activity printing red dye and a cleaning production process. The dye consists of three components with the structural formulas I, II and III, wherein the molar ratio of the components with the formulas I, II and III is 10-30:55-70:10-30. Under the synergistic effect of the components, the compound dye has the characteristics of bright coloured light, high solubility, good low-temperature solubility and good lifting power in deep colour, and can greatly reduce the service cost for printing and dyeing, lower the use amount of dye, reduce the three-waste emission for dye production and achieve the purposes of energy saving, emission reduction and cleaning production.

Description

technical field [0001] The invention belongs to the technical field of dyes, in particular to a reactive decal red dye, and at the same time provides a clean synthesis process for the dye. Background technique [0002] Traditional reactive red generally uses cyanuric chloride and H acid for primary condensation, coupling with diazonium anthranilate, adding o-chloroaniline for secondary condensation, and the product is salted out with sodium chloride, then dried and standardized After getting the product. The disadvantages of this process are: the pollution of three wastes is large, a large amount of process sewage is produced, the solubility of the product is low, only 80-100g / l (50°C), which cannot meet the printing process of dry powder mixing and automatic mixing systems, poor lifting power, dark color Print lift is poor. Contents of the invention [0003] The invention provides a new type of composite printing dye for the technical requirements of the current printin...
